How to set up ssd for Windows 10. How to optimize Windows for an SSD drive. What features should be disabled for stable SSD performance

Let's talk about how to set up an SSD for Windows 10. It's easy to start: in most cases, you don't need to tweak and optimize your solid state drives for a new OS. Moreover, according to Microsoft support staff, independent optimization attempts can harm both the operation of the system and the disk itself. However, some of the nuances should still be taken into account, and at the same time and at the same time clarify things related to how SSD drives work in Windows 10, we will talk about them. The last section of the article also contains information of a more general nature (but useful) related to the operation of solid-state drives at the hardware level and applicable to other versions of the OS. Immediately after the release of Windows 10, many instructions for optimizing SSDs appeared on the Internet, the vast majority of which are copies of manuals for previous OS versions, without taking into account (and, apparently, attempts to understand them) the changes that have appeared: for example, they continue to write that WinSAT needs to be started in order for the system to detect the SSD or disable automatic defragmentation (optimization) enabled by default for such drives in Windows 10.

Windows 10 default settings for SSD drives

Windows 10 is configured by default for maximum performance for solid-state drives (from the point of view of Microsoft, which is close to the point of view of SSD manufacturers), while it detects them automatically (without starting WinSAT) and applies the appropriate settings, no need to initiate this in any way.

Now for the points on how exactly Windows 10 optimizes SSD performance when it detects them.

1. Disables defragmentation (more on that later).
2. Disables the ReadyBoot feature.
3. Uses Superfetch / Prefetch - a feature that has changed since Windows 7 and does not require disabling SSDs in Windows 10.
4. Optimizes the power of the solid state drive.
5. TRIM is enabled by default for SSDs.

What remains unchanged in the default settings and causes controversy regarding the need to configure when working with SSD: file indexing, system protection (restore points and file history), caching records for SSD and clearing the write cache buffer, about this - after interesting information about automatic defragmentation.

System protection

Restore points automatically created by Windows 10, as well as File History, when the corresponding function is enabled, of course, are written to disk. In the case of SSDs, some recommend disabling system protection.

Some include Samsung, recommending doing this in both its Samsung Magician utility and the official SSD manual. At the same time, it is indicated that backups can cause a large number of background processes to run and decrease performance, although in fact system protection only works when changes are made to the system and during computer idle time.

Intel does not recommend this for its SSDs. Just like Microsoft does not recommend disabling system protection. And I wouldn't: a significant number of readers of this site could fix computer problems many times faster if they had Windows 10 protection enabled.

Read more about enabling, disabling and checking the status of system protection in the article.

Transferring files and folders to other HDDs

Another suggested option for optimizing SSD performance is to move custom folders and files, temporary files, and other components to a regular hard drive. As in the previous cases, this can reduce the amount of data recorded while reducing performance (when transferring temporary files and cache storage) or usability (for example, when creating thumbnails of photos from custom folders transferred to the HDD).

After purchasing a solid state drive (SSD), many people do not think about additional system settings, for optimal SSD performance requires 12 steps to unlock the full potential of your SSD. In this article, we will analyze all 12 steps, let's get started!

1. Enable AHCI mode

Extended Host Controller Interface ( AHCI) is a paramount feature to ensure that Windows OS will support all the functions of the SSD in the computer, especially the TRIM function so that the SSD does not directly access the affected sectors / pages on the drive.

To turn on AHCI, you need to log into the computer and turn it on somewhere in its settings. I cannot tell you exactly where, in each BIOS it may be in a different place. This is most likely enabled by default on new computers. It is recommended to enable this feature before installing the operating systemalthough you can turn it on after you have installed Windows.

2. Enable TRIM

We talked enough in the previous section about TRIM... This command gives a big boost in speed and stability.

Open a command prompt and enter the following command:

Fsutil behavior set disabledeletenotify 0

3. Disable System Restore

This is not necessary, but be aware that your SSD has a write limit and a space limit. System Restore slows down performance and requires SSD space. Why don't you just get rid of it?
Click the Start menu, right-click "Computer" - "Properties" and click the "System Protection" button:

Once in the window, click the "Customize" button, for example, like this:

Click the Disable System Protection button. Click "OK" and you're done!

4. Disable indexing

A significant portion of your SSD speed is consumed in indexing files for Windows search. This can be useful if you store everything on an SSD, there is a slowdown in the speed of work after reindexing, which happens every time you add new data to the disk. In order to disable indexing on SSD do the following:

Click the Start menu and select "Computer". Right click on the SSD drive and click Properties. Uncheck the box "Allow indexing of the contents of files on this drive in addition to file properties" and click "OK". After you do this, the operating system will apply this to all files and folders on the disk. If you see a dialog box saying that it cannot remove the file from the index, click Ignore All. This will streamline the process and ignore any errors.

5. Disable scheduled defragmentation

The SSD is a solid state hard drive, with no moving mechanical parts, so there is no need to defragment the drive offline, which is why we are going to disable that!

Click on Start, select "All Programs", "Accessories" click "System Tools", "Disk Defragmenter", and then click the "Schedule Setup" - "Disk Defragmenter" button:

Uncheck the Run as scheduled box. Click OK.

6. Windows swap file

The Windows paging file refers to a file on disk reserved for storing application components that would otherwise fit into physical memory. It is like a form of hard disk memory. Disabling the paging file on the solid state drive will greatly increase system speed. Don't do this if you only have one SSD drive. When paired with an SSD and an HDD, then you can easily configure the HDD to handle the paging file. The most ideal solution if you have two SSDs is to run the swap file on the first one to start Windows and to store files.

The process for configuring the swap file differs depending on the settings, so I'll show you how to get to the configuration window.

Right-click "Computer" on the Start menu and select "Properties." Click the Advanced System Settings button on the upper left side of the window and go to the Advanced tab. Click the Options button in the Performance section .:

Go to the "Advanced" tab and click the "Change" button, uncheck the "Automatically select the size of the paging file" and select "No paging file"

7. Disable sleep mode

Hibernation is at least 2 GB. If you want to keep this volume, write on the command line:

Powercfg -h off

8. Disable Prefetch and Superfetch

Windows places information in physical memory and virtual memory, owned by programs that you don't currently use, but use very often. This is known as "Prefetch" and "Superfetch." You can disable this through the registry editor:

HKEY_LOCAL_MACHINE \\ CurrentControlSet \\ Control \\ SessionManager \\ Memory Management \\ PrefetchParameters

as two values: EnablePrefetcher and EnableSuperfetch. Set both values \u200b\u200bto zero (0)!

9. Setting up caching

Disk caching can affect many users in different ways, check how your computer will work without caching, then with caching, this function is turned on very easily:

To get to the configuration window, right-click "Computer" on the Start menu and select "Properties." Click on Device Manager, expand Disk Devices, right-click the SSD, and click Properties. Select "Policy". In this tab, you will see an option labeled "Enable write caching to device."

Compare your SSD with and without option.

10. Disabling services for Windows Search and Superfetch

Even with the aforementioned tweaking of the registry and removal of the index, your computer can continue to load your hard drive. Press "Win + R" and see "services.msc" press "Enter". Find both services mentioned in the title of this section and disable them.

11. Disable ClearPageFileAtShutdown and LargeSystemCache

SSD runs on flash memory, making it easy to write data to disk. This way, files should not be erased when the computer shuts down. This will make the Windows shutdown process much faster. LargeSystemCache, on the other hand, exists primarily in the Windows Server versions, and tells the computer whether to use a large page cache on disk.

Both of these options can be found in the Registry Editor under

HKEY_LOCAL_MACHINE \\ CurrentControlSet \\ Control \\ SessionManager \\ Memory Management

Set them to 0.

12. Set "High performance" in power supply

Perhaps you notice when, after a long absence at the computer, the system slows down a little, for this you need to set high performance throughout the entire session.

To switch power settings, click the "System and Security" button and then click the "Power Options" button. Select "High Performance" from the list. You may need to click the Show Additional Schemes button to find it.

It's no secret that installing an operating system "from scratch" is fraught with many pitfalls that may not be sickly to spoil your nerves. This is especially true for installing an OS from a USB flash drive to an SSD solid state hard drive. Both media must be properly prepared and formatted, and the computer BIOS must be configured accordingly. Otherwise, annoying errors may occur: the installation program will not see the disk or will not start at all.

Installing Windows 10 on an SSD - sleight of hand and no cheating

In terms of operating system and computer hardware, a solid state drive (SSD) is no different from a classic hard drive with magnetic platters. Accordingly, installing an operating system on an SSD will be no different from installing on a regular hard drive.

The only nuances will be in setting up the disk subsystem for maximum performance and in creating partitions on the disk before installing the system. Since the disk is new, a clean copy of the OS will be installed.

Installing an OS on a blank disk will always be more difficult than an update that will download itself from the Internet and perform all the manipulations in the background, requiring literally a few clicks from the user.

Installing a clean copy consists of several sequential steps that should go smoothly and without errors. Let's get started?

Preparing bootable media (flash drive)

As practice shows, when installing Windows 10 on an SSD disk using a bootable DVD, errors often occur that prevent the normal installation of the OS. This happens especially often on laptops in which both the optical drive and the hard drive are connected to the same SATA controller: accessing the optical drive forces the computer to not optimally configure the controller, and the SSD may malfunction.

Therefore, to install the system, it is necessary to prepare a bootable USB flash drive, the installation from which will allow the process to be carried out quickly and without errors.

To prepare bootable media with the OS distribution, you need to download the Windows 10 distribution image, format the flash drive, and unpack the image to it. And if there are no questions about downloading, then further preparation of the flash drive can be carried out by a dozen different programs, similar in functions, but different in settings and interface.

We will focus on the official tool for deploying images from Microsoft - Microsoft USB / DVD download tool. The program is so simple that it is impossible to make a mistake when using it.

1. Find the Microsoft USB / DVD download tool on the Internet and download it.
2. Connect a USB flash drive to an available USB port to which the system image will be deployed. Insert into the USB port the flash drive to which you want to write the bootable Windows 10 image
3. Open "File Explorer" and remember the drive letter of the flash drive. In our case, this is the letter L.
   The connected flash drive was mounted in the file explorer, like drive L:
4. Run the Microsoft USB / DVD download tool.
5. Using the Browse button, select the ISO image with the operating system distribution kit and click Next.
   Step 1: choose the image to write to the USB flash drive
6. Select the type of media - USB Device (flash drive).
   Select the type of media you will make bootable using the USB / DVD download tool
7. Select the disk (flash drive) to deploy the media from the drop-down list and click the Begin copying button.
   Select your flash drive from the available devices and click the Begin copying button
8. Answer yes to the question about erasing the media. The program will format the USB flash drive and start copying files to it.
9. When the progress bar reaches 100% and a message appears about the successful creation of the media, the program can be closed.

The bootable USB flash drive has been successfully created, and the files of the Windows 10 distribution have been transferred to it

The bootable USB flash drive has been created, and you can start installing the operating system using it.

The occurrence of any errors during the operation of the program indicates a malfunction of the flash drive. Change the media to a known good one and repeat the bootable disk creation process.

In addition to its simplicity, this method is good because the use of an official Microsoft tool instead of one of the "free" programs guarantees a safe installation. Using it, you will not infect your computer with keyloggers or annoying adware modules.

Activating AHCI Mode

In order not to find yourself in a situation when the OS installer does not see the disk on which Windows 10 should be installed (this applies not only to SSDs, but in general to all hard drives with a SATA interface), using the BIOS settings, you must switch the SATA controller to AHCI mode ...

Preparing an SSD drive for OS installation

To avoid problems during installation of the Windows 10 operating system, the disk on which the installation will be carried out must be completely cleared of partitions. If this is not done, the system installation program may display a message stating that this disk cannot be used to install the OS. The reason will be the lack of space for creating service partitions, invisible to the user, but vital for the operating system.

To prevent this from happening, remove all partitions from the SSD disk.You can do this using the console command diskpart:

All partitions from the SSD drive are removed, and it is ready to install the Windows 10 operating system.

This method requires care and a lot of keystrokes, but it gives you full control over the process. If you are a fan of beauty and mouse clicks, then you can find hard disk management programs with a graphical interface.

Installing Windows 10 - step by step instructions

The bootable USB drive is created, the computer BIOS is configured, the SSD is pristine. We start the process of installing the operating system:

1. Boot the computer from the previously created flash drive with the Windows 10 distribution kit.
2. Select the default interface language and input keyboard, then click Next.
   Selecting the default system language and keyboard when installing Windows 10
3. Click the Install button to start the Windows installation.
   Start the Windows 10 installation with the "Install" button
4. Read and accept the terms of the license agreement. Without this, further installation will be impossible.
   Accept the license agreement to proceed with the installation
5. Select the installation type Custom: Windows Installation Only. A clean copy of the system can only be installed in this way.
   Installation of a "clean system" is possible only in the custom installation mode
6. Since we have previously cleared the target disk (SSD) from partitions, in the dialog for selecting a partition for installation, you will need to click the "Create" button, and then set the maximum possible size of the partition (it will be that by default). Together with it, the system will also create service sections for its own needs. They will not be visible in the "File Explorer":
   • section # 1: recovery environment. Contains the recovery environment necessary to "roll back" the system after critical errors or malware infection;
   • section # 2: system partition (EFI). Contains a boot configuration store (BCD) and files required to boot the operating system;
   • section # 3: MSR (system reserved). Required for service operations of embedded and third-party software (for example, to convert a simple disk to a dynamic one);
   • section # 4: operating system. This section will host the installed system. The space not occupied by the operating system will be available for installing applications and storing files.
7. After selecting the disk, the OS installation will begin. During the installation process, the screen may flicker and go out, the computer will automatically restart several times. This is required to complete some of the installation steps.
   Copying files and installing updates is the longest stage of OS installation
8. Now you need to select the basic settings for personalization and location, as well as connections and error reporting. The option "Use standard parameters (default)" will be most preferable for an inexperienced user. At this stage it is desirable to have a valid internet connection.
   In this window it is better to use the button "Use standard parameters"
9. After entering the user password, the operating system is ready to work.
   The system waits for user action on the lock screen

Proper preparation of two solid-state media: a bootable USB flash drive and an SSD drive is the key to a smooth and quick installation of Windows 10. In conclusion, I would like to dwell on the choice of the system distribution kit. We strongly discourage using self-made OS builds, which are often stored on torrent trackers. Their authors promise mountains of gold and extraordinary opportunities, but in fact, everything can result in viruses built into the system, pop-up ads and hardware failures. Use only original images from Microsoft, even if you are installing a "pirated" version of the OS.

Now is the time to talk about the correct operation of solid-state drives in Windows 10. According to Microsoft, the use of SSD on the "ten" does not require any settings or preliminary preparation of the system for installing such a digital storage medium, and changing the operating system parameters yourself can only harm the drive based on flash memory.

But, despite all the assurances of the Windows 10 developer, you should still pay attention to some points, and also study what the "ten" does to ensure maximum performance and save SSD resource.

With the release of Windows 10, guides on how to properly configure your system to optimize your solid state drives have appeared online. But in fact, all of them were copies of similar instructions for the "seven" and "eight", because in the last OS many actions are performed by the system automatically when the SSD is connected to the PC (disabling defragmentation, paging file).

What does the top 10 do to extend the life of an SSD without sacrificing its performance?

Initially, Microsoft configured the top ten so that when a solid-state storage medium was detected, it was already ready for use, without having to make any changes to the OS configuration. It is known from official sources that the list of settings when using drives based on flash memory includes:

• deactivation of defragmentation;
• using Superfetch;
• disabling ReadyBoost;
• optimization of the SSD power supply;
• activates the TRIM function for the drive.

Remembering the instructions for configuring other versions of Windows, you can note that indexing and caching of files are not disabled, as well as system protection (restore points are created regularly, reducing the working resource of the device). It's the same with folders for temporary files - you don't even get an offer to move them to your hard drive. Let's take a look at all this in order, starting with defragmentation.

Interesting facts about defragmentation

Defragmentation of the SSD in the top ten is disabled, but some optimization option is activated instead. Upon learning of this, many users immediately disable this function, some are studying the mechanism of its functioning. And, as it turns out, the implementation of block cleaning using TRIM technology is a useful function for solid-state digital data carriers.

Defragmentation of SSD in Windows 10 is carried out only when shadow copying is enabled (system protection is active) once a month, but for such drives its essence is not much different from defragmenting files on the HDD. In some cases, the absence of defragmentation of the file is useful (for example, when its size is subsequently increased).

What to manually disable and what not

Many users who read the old article on setting up Windows 10 to work with an SSD argue that SuperFetch, caching and file indexing should be turned off. These tips have a place in life, their implementation will lead to a loss of productivity and convenience of working at the computer.

Next, we will consider all the options for optimizing the operation of a solid-state drive in the top ten, noting that in order to obtain speed advantages during its operation, at least 15% of the disk space must be free. And this is very important.

Deactivating the paging file

If there is insufficient RAM for comfortable work and performing some tasks, it is advisable to use a paging file.

This fact is also supported by the fact that the mechanism of its operation implies the minimum number of calls to the pagefile.sys file for writing, regardless of the amount of installed and free RAM. The number of read operations exceeds the number of writes for about 40 times.

With the paging file disabled, even with 8 GB or more of RAM, some "heavy" applications refuse to start (for example, Adobe Premier) or regularly crash. This may be the price to pay to increase the SSD resource.

Disable hibernation

Another controversial feature is the deactivation of the computer's ability to enter hibernation mode. It is also used to quickly start Windows 10. For this, the file hiberfil.sys is created on the system volume. The “ten” writes the contents of RAM (in case of hibernation) or files necessary for a quick start of the system into it. The size of the file takes up the same space as the RAM installed on the computer, and the amount of data written to it does not exceed the current size of the used RAM.

If for a computer deactivating the function of putting the system into hibernation mode is not critical, then for laptop owners this will result in an accelerated discharge of the battery and the need to wait for the device to turn on. The process can be delayed with a large number of programs placed in startup, especially on old devices. In the case of a PC, waiting for it to fully load is important if you want to extend the life of an expensive SSD.

It is also possible to reduce the size of hiberfil.sys by disabling hibernation without disabling fast boot.

System Restore

When the File History function is enabled and the system automatically generates rollback points before performing operations affecting the system (installing / removing software), the physical resource of the SSD is reduced. Therefore, it is recommended to disable file history and restore points creation. But such a careful attitude to the drive can result in data loss or the need to reset the system in the event of a serious failure and the inability to roll back to its previous state.

When using a Korean Samsung SSD, this can be done using the Samsung Magician application. Backing up in the background can degrade the performance of the SSD when performing many other tasks in the case of working with the media file system. Therefore, data backups should be performed when the computer is idle.

Intel and Microsoft strongly advise against disabling the operating system protection feature. With it, you can quickly return your computer to a working state without loss or with minimal loss of user data.

Transferring temporary and user files to your hard drive

Another option for reducing wear and tear on a solid-state drive is to move temporary files and user data to partitions physically located on the hard drive. Thus, multiple overwriting of work files and their regular changes (for example, those stored on the desktop or in My Documents) will slightly reduce the number of writes to the SSD.

Usually, solid-state drives are used as system drives, so storing a multimedia library or a catalog of images on them is not advisable (this does not apply to games). Indeed, during the optimization process, many of the files for which the reading speed does not matter much are affected, their blocks are moved many times.

Superfetch, file indexing for faster searches, record caching and more

There are more problems using or disabling these features than others. Different manufacturers place conflicting data on their resources. It is up to the user to decide which of them to believe, but it is imperative to read the recommendations of the leading SSD developers.

According to Microsoft, Prefetch and Superfetch also work well on SSDs, but have undergone significant changes on Windows 10. Samsung says that SSDs should not be used with Superfetch enabled.

As for clearing the cache buffer, the information here is also radically different, even within the same SSD manufacturer without reliable information due to one point of view or another. The cache buffer itself can be used; this will not in any way affect the life of the flash memory.

Search and indexing

In Windows 10, the Indexing Service is more active in indexing for instant searches, but without it, the always visible search icon will be useless, and you won't be able to instantly launch a system tool or open a frequently used file. Whether it is worth slightly extending the operating time of the SSD at the expense of convenience - decide for yourself.

As already mentioned, for high-performance operation of an SSD, it must have about 15% or more of free space, which is due to the peculiarities of storing digital data on such media. Many SSD developers supply proprietary utilities whose task is to reserve this ~ 15% of the space by creating a hidden volume.

The drive must be in AHCI mode. This can be checked in the Task Manager (invoked via Win → X).

It is highly recommended to connect SSDs, no matter who the manufacturer is, to the high-speed SATA interface of the third generation, which does not use third-party controllers. It happens that the motherboard has a chipset for an Intel or AMD processor and additional ports on third-party controllers.

The SSD should be connected, of course, to the first. They can be identified both by the markings on the motherboard, and by using the operating instructions for the motherboard or laptop.

Periodically visit your digital media manufacturer's website or device support resource and check for the latest firmware. Updating software in a positive way affects the performance of the hardware, this applies not only to solid state drives.

To summarize, we can say the following: for newbies, Windows 10 is well configured in terms of minimizing unnecessary write operations. It makes little sense to interfere with its settings, but experienced users can transfer temporary files to the hard drive and deactivate several functions (indexing, hibernation) to extend the life of the SSD at the expense of the convenience of working on the computer.

Good afternoon dear readers, today we will analyze how much free space you need for ssd to install the Windows operating system, how to predict further data growth so that everything works like a clock and does not disable the device.

SSD (Solid state drive) is a drive that does not have moving parts like a regular hard drive. An SSD uses flash memory to store memory. In simple words, this is such a big flash drive that has become very firmly established in our lives.

Why do you need an ssd disk

And so we figured out the definition, now let me answer the question of what ssd is needed for and where it is used. Literally 5 years ago, all computers and server solutions, as a disk subsystem, had HDD hard drives, which have already rested on their performance due to their design and spindle speed. The world demanded further development, especially in the field of mobile devices, it was they who became the locomotive that pushed through the new technology, Solid state drive. SSD drives brought us:

• hundreds of thousands of input-output operations (IOPS) compared to HDDs with a maximum of 150 iops,
• reduced electrical consumption,
• reduced the required amount of physical space inside servers and computers

• Ceased to bask
• They have become more durable and not critical to falling or light impact on them
• Reduced weight of devices
• Laptops have increased battery life

I think you now understand why you need an ssd disk to make your life more comfortable and less nervous. How many times have I seen people at work, whose hard disks began to die, having checked their condition with a special utility, I stated that the Khan's disk will soon have nothing to change, be patient. And now a man with gritting teeth and wild brakes of the operating system tried to work, getting irritated every minute, more and more. With ssd, this does not threaten, it only has a 5-year warranty period from the manufacturer, and with average use in companies, it will live all 8-10 years, saving a lot of money for employers.

Ssd volume in 2017-18

And so we figured out the question of why an ssd drive is needed, now let's talk about its volume, which interests the modern user most of all. When I told you above about the comparison of hdd and ssd, about all its advantages, I forgot to mention, two significant disadvantages that are still holding back its massive ousting from the market of servers and personal computers:

1. Much smaller volume compared to HDD
2. The price can be several times higher than that of hard drives

Although the volume of SSDs increases and the price per gigabyte decreases every year, they still leave much to be desired, HDDs according to the formula volume and price per gigabyte are still winning. In such situations, they come to a compromise, in which a solid-state disk (ssd) is used for a clean installation of Windows 7 and higher, and a regular HDD 3.5 is used for any data.

At the moment, the largest ssd volume is 15 TB and it costs $ 10,000, which only large companies can afford for very fast RAID arrays. This is what this solid state drive looks like from Samsung.

But this, as it turns out, is not the limit, Samsung is already developing ssd with a volume of 60 TB and this is already a very serious volume, I think that in the next 5-7 years this market will grow strongly and make the price of SSDs less than that of hard drives.

How much ssd is needed for windows 10

Let's now figure out how large a solid-state drive should be with Windows 10 Creators Update installed. Here I can cite figures from my practice, which includes the maintenance of more than 700 computers with this OS.

• For Windows 10 itself, you will need a 20GB ssd solid state drive
• At the time of installing updates, the Windows 10 operating system may require an additional 15 GB from you, just an example of the transition from threshold 2 to the anniversary update, at this moment the Windows.old folder is created so that the user can roll back the system at any time.
• Third-party programs from 10 GB
• Space for temporary files, about 5-10 GB

To summarize, for Windows 10, the volume of a solid-state drive ssd in the amount of 120 GB or more will suit you, at current prices, it will cost you from 3200 rubles, which is not very expensive, the only thing you have to do is to make tuning to reduce its wear and buy an additional screw for your main files (Music, photo, video)

How much ssd is needed for windows 7 and 8.1

Let's now figure out how large a solid-state drive should be with Windows 7 or 8.1.

• The seven itself will require 12-15 GB, but with constant updates, the folder can grow up to 30 GB, so you will have to constantly clean up old updates.
• Office suite Microsoft Office will require another 5-7 GB of space from you
• Third-party programs from 10 GB

To summarize, the seven will fit for 60 GB, but I advise you not to screw up and buy 120 GB. The most joyful thing is that this technology only improves every year, we will wait. Today we examined what an ssd drive is and why you need it, if you have questions, then write them in the comments, I will try to answer.
